Singing Sand

Also known as sounding sand, singing sand is sand that emits musical, humming, whistling, or crunching sounds when disturbed. Although it has been studied extensively, the phenomenon is not completely understood. When it occurs near dunes, the sound accompanies a slumping or avalanching movement of the sand, usually triggered by wind or by someone walking near the crest. Different patches of sand are even said to "sing" at different frequencies. What are some locations where the sand sings? More...

Singing sands, sands that emit audible sounds when in motion. This phenomenon occurs in many parts of the world and has been known for many years. The sound may be produced by a footstep or by the slippage of the sand downslope. The sounds emitted may vary with different sands from a roar to musical quality, and they also vary according to the volume and velocity of the sand involved. The sand must be extremely dry in order for sound to be emitted. Singing sands are especially well sorted according to size and are highly spherical, which allows them to be very compact and to shear along thin planes. Although the exact methods and causes of sound emissions from such sands are not known, some geologists believe it is due to one layer of sand slipping over another.
